Exhaust valve for piston internal combustion engine

The exhaust valve has a valve member (2) which opens away from the combustion chamber (4) of the engine cylinder and which is biased for opening by the gas pressure prevailing in the combustion chamber. The valve is kept closed by an opposed hydraulic pressure which in a holding chamber (12) acts on a holding piston (11) secured to the spindle (10) of the valve member. When the valve is to be opened, the pressure in the holding chamber is relieved and one or more valve controlled flow passages (35, 36) are opened, through which hydraulic liquid flows from the holding chamber to a reservoir (14) defined by a piston (13) secured to the valve spindle (10). The two pistons (11 and 13) are preferably of substantially equal size. When the exhaust valve is to be closed a hydraulic pressure is applied to a substantially smaller closing piston (17) which is also secured to the valve spindle (10). During the closing movement hydraulic liquid flows from the reservoir back to the holding chambre and after the closing movement that chamber is again connected to the hydraulic pressure which ensures that the valve member is maintained in its closed position against the gas pressure.

Internal combustion engine having a transitionally segregated combustion chamber

A combustion chamber is provided within an internal combustion engine, the combustion chamber including a cylinder head having an internal bore with an open end and a closed end, and a piston which reciprocates within the internal bore between a TDC position near the closed end and a BDC position, with a compression end facing the closed end. Poppet valves on the closed end and ports on the internal bore can control the flow of gasses into, and from, the combustion chamber. The combustion chamber is stratified when the compression end is positioned within a stratified distance of the closed end. When stratified, the combustion chamber is comprised of a central combustion region, a perimeter squish region, and a transfer passage between the regions. A direct fuel injector injects fuel into the central combustion region, mixing fuel with inducted gasses prior to combustion. The combustion chamber can be thermally insulated.

The split-cycle engine includes a crankshaft. The compression piston is received in the compression cylinder and operably connected to the crankshaft. The crossover passage interconnects the compression cylinder and the expansion cylinder. The crossover passage includes a crossover compression (XovrC) valve and a crossover expansion (XovrE) valve defining a pressure chamber therebetween. The crossover compression valve is timed to open the crossover compression valve when the pressure in the compression cylinder is less than the upstream pressure in the crossover passage at the crossover compression valve.

Fast valve and actuator

A fast-acting valve includes a valve body and a spool slidably mounted within the valve body between first and second limit positions. Both the spool and the valve body have a flow passage which come into alignment with the valve spool at a position intermediate the first and second limit positions and spaced therefrom by a given distance. That given distance allows the spool member to accelerate in travel from the first and second limit positions to the valve open position so that the opening of the valve (and closing) occurs quite quickly. Reciprocating movement of the valve spool relative to the valve body can be provided by springs mounted in opposing ends of the valve body bore in cooperation with solenoids mounted on opposing sides of the valve body. The fast-acting valve may be modified into the form of poppet valve or a cartridge valve.

Cold air super-charged internal combustion engine, working cycle and method

Working cycle for internal combustion engines, with methods and apparatuses for managing combustion charge density, temperature, pressures and turbulence (among other characteristics). At least one embodiment describes a supercharged internal combustion engine in which a supercharging portion of air is compressed, cooled and injected late in the compression process. A sub-normal compression ratio or low “effective” compression ratio initial air charge is received by a cylinder/compression chamber on the engine intake process, which during compression produces only a fraction of heat-of-compression as that produced by a conventional engine. During compression process, dense, cooled supercharging air charge is injected, adding density and turbulence above that of conventional engines with low “effective” compression ratio for this portion of air charge also. Compression continues and near piston top dead center, the air charge being mixed with fuel is ignited for power pulse followed by scavenging.

Spark ignition type 4-cycle engine

【課題】 シリンダーの外側に拡張された燃焼室内壁の表面積の増加による冷却損失量の増加を補償する手段を提供する。 【解決手段】 主シリンダー１の外側に拡張された燃焼室３の部分に、第二排気茸弁９が設置される。バルブ・カバー７は、副シリンダー４内を往復運動し、第二排気茸弁９の底面を覆う。ピストン２の上面に面して第一排気茸弁１０と吸気茸弁１１が設置される。第二排気茸弁９が開弁して、高温で高圧の燃焼ガスが流失し始めた後に、第一排気茸弁１０が開く。すると、第一排気茸弁１０の温度が低下し、ノッキングが発生し難くなり、圧縮比を増加できる。すると、前記ピストンの仕事量が増加する。この増加した仕事量が燃焼室内壁の表面積の増加による冷却損失量の増加を補償する。 【選択図】 図３ PROBLEM TO BE SOLVED: To provide a means for compensating for an increase in cooling loss due to an increase in surface area of a combustion chamber wall extended outside a cylinder. SOLUTION: A second exhaust soot valve 9 is installed in a portion of a combustion chamber 3 extended outside the main cylinder 1. The valve cover 7 reciprocates in the sub cylinder 4 and covers the bottom surface of the second exhaust soot valve 9. A first exhaust soot valve 10 and an intake soot valve 11 are installed facing the upper surface of the piston 2. After the second exhaust soot valve 9 is opened and high-temperature and high-pressure combustion gas begins to flow away, the first exhaust soot valve 10 is opened. As a result, the temperature of the first exhaust soot valve 10 decreases, knocking hardly occurs, and the compression ratio can be increased. Then, the work amount of the piston increases. This increased work compensates for the increased cooling loss due to the increased surface area of the combustion chamber wall. [Selection] Figure 3

Harmonic engine

An engine based on a reciprocating piston engine that extracts work from pressurized working fluid. The engine includes a harmonic oscillator inlet valve capable of oscillating at a resonant frequency for controlling the flow of working fluid into of the engine. In particular, the inlet valve includes an inlet valve head and a spring arranged together as a harmonic oscillator so that the inlet valve head is moveable from an unbiased equilibrium position to a biased closed position occluding an inlet. Upon releasing the inlet valve the inlet valve head undergoes a single oscillation past the equilibrium positio to a maximum open position and returns to a biased return position close to the closed position to choke the flow and produce a pressure drop across the inlet valve causing the inlet valve to close. Protrusions carried either by the inlet valve head or piston head are used to bump open the inlet valve from the closed position and initiate the single oscillation of the inlet valve head, and protrusions carried either by the outlet valve head or piston head are used to close the outlet valve ahead of the bump opening of the inlet valve.
